Some scientists believe that the neurotransmitters are just links in a chain of reactions and that the real master molecules of mood reside higher up in that chain. One leading candidate: a substance called corticotropin- releasing hormone, or crh, which is pumped directly into the spinal fluid and thus bathes the entire brain at once. Discovered in 1981 by researchers studying the biochemistry of stress, crh is known to promote vigilance and decrease interest in food and sex when administered in small doses. In higher doses, it triggers anxiety. When Philip Gold, chief of the clinical neuroendocrinology branch...
...roommate Christopher, who was taking Expos with another professor, showed me his first piece. Christopher is a computer science major with ambitions to study artificial intelligence. I was flattered when he asked me to read his work--itseemed he wanted my approval. Turns out he hadwritten the most fluid, mature, sensitive pieces Ihad seen in recent memory. And writing wasn't evenhis thing. That killed...
...many women really match this pitiable description? But if Heyn is right -- if, in fact, a large cross section of American wives suffer from Donna Reed syndrome -- the news here is not that women have extramarital affairs and feel good about their infidelities, as Heyn's fluid narrative suggests. Rather, the news is that after 30 years of battling to shore up women's self-esteem and break down entrenched sex roles, the feminist movement has achieved nothing. That women have learned nothing. That women still bask in a sense of worthlessness that sounds ominously like Betty Friedan's "problem...
Simply defined, sports drinks replenish the fluid, minerals and energy lost during exercise. Long familiar to athletes, Gatorade has become highly visible to sports fans, in the form of the ubiquitous large green-and-orange vats of the drink in dugouts or near team benches at major league events. Hardly a postgame interview passes without a shot of the MVP taking a sip from a paper cup labeled "Gatorade," which is, after all, the official sports drink of major league baseball, the N.F.L., the N.B.A. and the National Hockey League. "Gatorade defines the category," says Jesse Meyers, publisher of Beverage...
Competitors disagree. Still, while percentages of ingredients vary from brand to brand, all the drinks contain water (for fluid replacement), salt and potassium (to maintain the body's fluid-electrolyte balance), and sugar (for quick energy and flavor). Do they actually work? Manhattan internist Peter Bruno, the team doctor for basketball's New York Knicks, gives a qualified yes. "If you work out more than an hour, you must replace both water and sodium," says Bruno. "But when you exercise for less than an hour, you only need to replace the water." Most medical experts agree that for those...
